About 'Bach Six Little Prelude no4. BWV942'
Bach, Johann Sebastian (biography)
21 March 1685 , Eisenach
28 July 1750 , Leipzig
One of the greatest composers of all time. Bach wrote hundreds of pieces for organ, choir, as well as many other instruments. He spent most of his life as a church organist and a choir director. His music combines profound expression with clever musico-mathematical feats, like fugues and canons in which the same melody is played against itself in various ways.
